We just redecorated our living and dining rooms last month and the very next day after having new carpet put down Ripley backed up to a freshly painted wall and sprayed right in front of me. I immediately freaked out. Not much hit the carpet but the wall was pretty wet. I cleaned everything with Natures Miracle several times over a couple of weeks and the smell is gone. I also ran out and bought Feliway spray and a Comfort Zone Feliway 30 day plug in. It seems to be working.

Ripley tried to spray two more times after that but I caught him and sprayed a water bottle at him to get him to stop (luckily he hadn't gotten any urine out yet). I then took him straight to his litter box and he would get in and use it. I've also spent a lot of extra time and attention on him. With all these things, especially spraying the feliway around the room twice a day, I think it has worked and I know he hasn't sprayed anything since. I just bought another plug in and another bottle of spray to continue using over the next month. It's expensive but cheaper than my new carpet and furniture so it's worth it.

Good luck!
